a group from NASA’s COMPASS team detailed several scenarios of the infrastructure and technologies it would take to make an in-situ resource utilization (ISRU) system that could provide enough propellant to get astronauts back to a Mars orbit where they could meet up with an Earth return vehic...
Mars - Red Planet, Orbit, Moons: Mars is the fourth planet out from the Sun. It moves around the Sun at a mean distance of 228 million km (140 million miles), or about 1.5 times the distance of Earth from the Sun. Because of Mars’s relatively elongated
The picture, taken Wednesday, shows sunlight just coming across the surface of Mars. It shows Mars' north pole, as well as Mars' largest volcano, Olympus Mons. The image comes from its “Amal,” or “Hope,” space probe. The probe swung into orbit around Mars on Tuesday in a triu...
